Summary: Ref T4398. Prevent users from brute forcing multi-factor auth by rate limiting attempts. This slightly refines the rate limiting to allow callers to check for a rate limit without adding points, and gives users credit for successfully completing an auth workflow.
Test Plan: Tried to enter hisec with bad credentials 11 times in a row, got rate limited.

Summary:
Ref T4398. Allows auth factors to render and validate when prompted to take a hi-sec action.
This has a whole lot of rough edges still (see D8875) but does fundamentally work correctly.
Test Plan:
- Added two different TOTP factors to my account for EXTRA SECURITY.
- Took hisec actions with no auth factors, and with attached auth factors.
- Hit all the error/failure states of the hisec entry process.
- Verified hisec failures appear in activity logs.

Summary:
Ref T4398. This adds a settings panel for account activity so users can review activity on their own account. Some goals are:
- Make it easier for us to develop and support auth and credential information, see T4398. This is the primary driver.
- Make it easier for users to understand and review auth and credential information (see T4842 for an example -- this isn't there yet, but builds toward it).
- Improve user confidence in security by making logging more apparent and accessible.
Minor corresponding changes:
- Entering and exiting hisec mode is now logged.
- This, sessions, and OAuth authorizations have moved to a new "Sessions and Logs" area, since "Authentication" was getting huge.
Test Plan:
- Viewed new panel.
- Viewed old UI.
- Entered/exited hisec and got prompted.

Summary:
Ref T4398. This is roughly a "sudo" mode, like GitHub has for accessing SSH keys, or Facebook has for managing credit cards. GitHub actually calls theirs "sudo" mode, but I think that's too technical for big parts of our audience. I've gone with "high security mode".
This doesn't actually get exposed in the UI yet (and we don't have any meaningful auth factors to prompt the user for) but the workflow works overall. I'll go through it in a comment, since I need to arrange some screenshots.
Test Plan: See guided walkthrough.

Summary:
Ref T4339. Ref T4310. Currently, sessions look like `"afad85d675fda87a4fadd54"`, and are only issued for logged-in users. To support logged-out CSRF and (eventually) external user sessions, I made two small changes:
- First, sessions now have a "kind", which is indicated by a prefix, like `"A/ab987asdcas7dca"`. This mostly allows us to issue session queries more efficiently: we don't have to issue a query at all for anonymous sessions, and can join the correct table for user and external sessions and save a query. Generally, this gives us more debugging information and more opportunity to recover from issues in a user-friendly way, as with the "invalid session" error in this diff.
- Secondly, if you load a page and don't have a session, we give you an anonymous session. This is just a secret with no special significance.
This does not implement CSRF yet, but gives us a client secret we can use to implement it.
Test Plan:
- Logged in.
- Logged out.
- Browsed around.
- Logged in again.
- Went through link/register.

Summary:
Ref T4310. Fixes T3720. This change:
- Removes concurrent session limits. Instead, unused sessions are GC'd after a while.
- Collapses all existing "web-1", "web-2", etc., sessions into "web" sessions.
- Dramatically simplifies the code for establishing a session (like omg).
Test Plan: Ran migration, checked Sessions panel and database for sanity. Used existing session. Logged out, logged in. Ran Conduit commands.

Summary:
Ref T3720. Ref T4310. Currently, we limit the maximum number of concurrent sessions of each type. This is primarily because sessions predate garbage collection and we had no way to prevent the session table from growing fairly quickly and without bound unless we did this.
Now that we have GC (and it's modular!) we can just expire unused sessions after a while and throw them away:
- Add a `sessionExpires` column to the table, with a key.
- Add a GC for old sessions.
- When we establish a session, set `sessionExpires` to the current time plus the session TTL.
- When a user uses a session and has used up more than 20% of the time on it, extend the session.
In addition to this, we could also rotate sessions, but I think that provides very little value. If we do want to implement it, we should hold it until after T3720 / T4310.
Test Plan:
- Ran schema changes.
- Looked at database.
- Tested GC:
- Started GC.
- Set expires on one row to the past.
- Restarted GC.
- Verified GC nuked the session.
- Logged in.
- Logged out.
- Ran Conduit method.
- Tested refresh:
- Set threshold to 0.0001% instead of 20%.
- Loaded page.
- Saw a session extension ever few page loads.

Summary: Ref T4310. Ref T3720. Session operations are currently part of PhabricatorUser. This is more tightly coupled than needbe, and makes it difficult to establish login sessions for non-users. Move all the session management code to a `SessionEngine`.
Test Plan:
- Viewed sessions.
- Regenerated Conduit certificate.
- Verified Conduit sessions were destroyed.
- Logged out.
- Logged in.
- Ran conduit commands.
